Wafer (electronics) - Wikipedia
In electronics, a wafer (also called a slice or substrate) [1] is a thin slice of semiconductor, such as a crystalline silicon (c-Si, silicium), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as the substrate for microelectronic devices built in and upon
How Are CPUs Actually Made? - How-To Geek
2019年3月4日 · The wafer is coated with a material called a photoresist, which responds to the light and is washed away, leaving an etching of the CPU that can be filled in with copper or doped to form transistors. This process is then repeated many times, building up the CPU much like a 3D printer would build up layers of plastic.
How "Wafer-Scale" CPUs Could Revolutionize Supercomputers - How-To Geek
2022年5月24日 · A wafer-scale CPU effectively combines the processing power of dozens or hundreds of computers into a single integrated circuit, driven by one power supply, all housed in a single chassis. Even better, you can still network multiple wafer-scale computers together to create a traditional supercomputer, but exponentially faster.
